The Alopecia Areata Severity and Morbidity Index (ASAMI) Study: Results From a Global Expert Consensus Exercise on Determinants of Alopecia Areata Severity.

Importance: Current measures of alopecia areata (AA) severity, such as the Severity of Alopecia Tool score, do not adequately capture overall disease impact. Objective: To explore factors associated with AA severity beyond scalp hair loss, and to support the development of the Alopecia Areata Severity and Morbidity Index (ASAMI). Evidence Review: A total of 74 hair and scalp disorder specialists from multiple continents were invited to participate in an eDelphi project consisting of 3 survey rounds. The first 2 sessions took place via a text-based web application following the Delphi study design. The final round took place virtually among participants via video conferencing software on April 30, 2022. Findings: Of all invited experts, 64 completed the first survey round (global representation: Africa [4.7%], Asia [9.4%], Australia [14.1%], Europe [43.8%], North America [23.4%], and South America [4.7%]; health care setting: public [20.3%], private [28.1%], and both [51.6%]). A total of 58 specialists completed the second round, and 42 participated in the final video conference meeting. Overall, consensus was achieved in 96 of 107 questions. Several factors, independent of the Severity of Alopecia Tool score, were identified as potentially worsening AA severity outcomes. These factors included a disease duration of 12 months or more, 3 or more relapses, inadequate response to topical or systemic treatments, rapid disease progression, difficulty in cosmetically concealing hair loss, facial hair involvement (eyebrows, eyelashes, and/or beard), nail involvement, impaired quality of life, and a history of anxiety, depression, or suicidal ideation due to or exacerbated by AA. Consensus was reached that the Alopecia Areata Investigator Global Assessment scale adequately classified the severity of scalp hair loss. Conclusions and Relevance: This eDelphi survey study, with consensus among global experts, identified various determinants of AA severity, encompassing not only scalp hair loss but also other outcomes. These findings are expected to facilitate the development of a multicomponent severity tool that endeavors to competently measure disease impact. The findings are also anticipated to aid in identifying candidates for current and emerging systemic treatments. Future research must incorporate the perspectives of patients and the public to assign weight to the domains recognized in this project as associated with AA severity.

Development of Consensus Recommendations on the Management of Vitiligo and the Role of Decapeptide in Vitiligo by the Delphi Method.

Background: Treatment of vitiligo is still a challenge in dermatology. Literature is sparse on the definitive clinical role of basic fibroblast growth factor (bFGF) in vitiligo patients. Aims: We decided to generate a consensus in an attempt to answer some critical questions related to the management of vitiligo and the role of bFGF. Materials and Methods: A Delphi method among 21 experts across India was conducted. A consensus (agreement was 75% or greater) was taken on 27 statements on the prevalence, epidemiology, and treatment of vitiligo and the role of bFGF in the management of vitiligo. The consensus process was completed after two rounds. Results: Topical corticosteroid therapy is the first-line therapy for vitiligo; however, its adverse effects are widely known, especially in sensitive areas. Topical calcineurin inhibitors are preferred in stable vitiligo of the face, neck, genitals, or intertriginous regions as an alternative to topical corticosteroids. Topical bFGF is a relatively newer therapy with a promising role in stable vitiligo. bFGF is safe and effective in inducing repigmentation of vitiligo lesions. Combination therapy of bFGF with other topical therapies, phototherapy, and surgical procedures can be beneficial in patients of vitiligo. Conclusion: This consensus would complement the currently available literature on bFGF and help the practitioner to recognize the unmet need in the treatment of vitiligo.

Monitoring of Vitiligo Patches Over Six Months to Validate Dermoscopic Findings of Lesional Stability.

INTRODUCTION: Previously laid down criteria for lesional stability of vitiligo are inconsistent. Longitudinal data on correlation between dermoscopic features of vitiligo and disease activity is limited. OBJECTIVES: To sequentially determine the dermoscopic features of vitiligo and to assess their association with the dynamic nature of the vitiligo patch. METHODS: Sixty patients with 200 vitiligo patches fulfilling the inclusion criteria on medical therapy were subjected to sequential clinical and dermoscopic examination for 6 months. Baseline lesional photographs, dermoscopy and tracing of the patch was made and repeated at 6 months. The follow up tracing was superimposed onto the baseline tracing. Based on the increase or decrease in size, their outcomes were grouped as responsive, progressive and quiescent. Paired analysis of dermoscopic features was done between baseline, and their follow up after 6 months. RESULTS: Well defined border was associated with static nature of the vitiligo patch and ill-defined borders and trichrome pattern depicted its dynamic nature. Statistically significant increase in leukotrichia and satellite lesions amongst progressive patches and a decrease amongst responsive patches was observed. Pigment network changes were statistically significant for both responsive and progressive patches. Satellite lesions and micro-Koebner's phenomena was suggestive of progressive disease, while perifollicular pigmentation and perilesional hyperpigmentation was suggestive of re-pigmenting disease and proved to be an early marker for response to therapy. CONCLUSIONS: Repeated dermoscopic evaluation of lesions in a serial manner to assess disease activity helps understand their evolving nature and is a valuable tool in planning appropriate further treatment.

Cross-sectional study to evaluate the utility of elastic tissue staining in primary cicatricial alopecia.

BACKGROUND AND AIMS: Diagnosing end-stage primary cicatricial alopecia (PCA) on routine histology is challenging since the major diagnostic feature (inflammatory infiltrate) may be minimal or absent. This study aimed to assess various staining patterns and diagnostic utility of elastic tissue staining by Verhoeff-Van Gieson (VVG) method and trichoscopy in PCA. STUDY DESIGN: Cross-sectional study. METHODS: Fifty-three patients clinically diagnosed with PCA underwent biopsy and trichoscopy in this cross-sectional study. Clinically active edge, if present, was biopsied. Twenty serial tissue sections were stained using H&E and VVG stain. Clinicopathological diagnoses were lichen planopilaris (LPP), discoid lupus erythematosus (DLE), folliculitis decalvans and unclassified PCA (UPCA) in 30 (56.6%), 11 (20.75%), 1 (1.9%) and 11 (20.75%) patients, respectively. Utility of VVG stain was ascertained considering clincopathological correlation (CPC) as the reference standard. Association of characteristic trichoscopic and VVG staining patterns was ascertained. RESULTS: Diagnostic definition was achieved on VVG staining in 19/30 sections of LPP (wedge-shaped pattern) with 63.33% sensitivity; 7/11 cases of DLE (absent upper and mid dermal elastic fibres) with 63.64% sensitivity and 7/11 cases of UPCA (wedge-shaped pattern-3/7; recoil pattern-4/7). Routine histology suggested diagnosis only in 13/53 sections (24.52%). However, diagnosis on VVG staining corresponded with diagnosis on CPC in 33/53 cases (62.3%). Comparison of H&E versus VVG stain both overall and in the LPP and UPCA cohorts proved utility of VVG staining using Fisher's exact test (p<0.05). Statistical significance was also noted when trichoscopy was correlated with patterns on VVG staining (p<0.05). CONCLUSION: Increased diagnostic yield is noted with trichoscopy and VVG stain in PCA especially when routine histopathology is non-diagnostic.

A Practical Approach to the Treatment of Alopecia Areata.

Alopecia areata is an autoimmune condition which usually presents as non-scarring patchy alopecia. The disease has varied clinical presentations ranging in severity from patchy circumscribed alopecia, reticular pattern, ophiasis, sisaipho, diffuse, or incognito type to alopecia totalis and alopecia universalis. The various available treatment options include topical/intralesional steroids, topical immunotherapy/contact irritants, systemic steroids, and steroid-sparing agents like cyclosporine, azathioprine, methotrexate, and the JAK-STAT inhibitors. This article aims at providing practical tips to the clinicians based on published data and author's clinical experience which can help them in deciding what and when to choose in a given clinical scenario of AA.

All that a Dermatotrichologist needs to know about Hair Camouflage: A Comprehensive Review.

Hair loss can impact a person's quality of life in ways incomprehensible. People value hair for different reasons, but value it nonetheless. There is a myriad of conditions that impede hair growth or cause hair to grow in an unattractive manner such as androgenetic alopecia, alopecia areata, and chemotherapy-induced hair loss. For conditions like cicatricial alopecia, there are hardly any options available once permanent loss of hair sets in. The role of hair transplantation too is limited in such cases where the donor area has been compromised. Thus, addressing the concern of hair loss and presenting all possible options available even after medical and surgical options flounder due to their limitations is a responsibility every dermatotrichologist carries and a plethora of camouflage options are available to improve the appearance of hair right from hairpieces to more permanent methods like scalp micropigmentation.

SULT1A1 (Minoxidil Sulfotransferase) enzyme booster significantly improves response to topical minoxidil for hair regrowth.

BACKGROUND: Minoxidil is a widely used over-the-counter topical treatment for hair loss. The response rate for topical minoxidil is relatively low. Minoxidil is a pro-drug, converted to its active form, minoxidil sulfate, by SULT1A1 enzymes located in the scalp. Recently, a novel topical formula that increases the activity of SULT1A1 in hair follicles was reported. AIMS: To evaluate any benefit of applying the SULT1A1 enzyme booster prior to daily 5% minoxidil treatment. METHODS: Male androgenic alopecia patients were recruited to a randomized blinded placebo-controlled study. Patients were randomized to receive 5% topical minoxidil plus the novel formula or minoxidil plus a sham adjuvant. Patient's hair growth was monitored using global photography over 60 days. RESULTS: Twenty-four males with androgenic alopecia (Norwood scale average 4.4, range 2-6) were randomized and completed the trial: 12 in the active arm and 12 in placebo. 75% of the subjects who used the SULT1A1 adjuvant with their daily minoxidil treatments for 60 days regrew hair versus 33% of those using the placebo adjuvant (p = 0.023). CONCLUSIONS: In a small cohort of androgenetic alopecia men, adding the SULT1A1 adjuvant to their daily minoxidil treatment regimen improved hair regrowth.

Trichodynia and telogen effluvium in COVID-19 patients: Results of an international expert opinion survey on diagnosis and management.

BACKGROUND: The cutaneous manifestations of COVID-19 may be useful disease markers and prognostic indicators. Recently, postinfectious telogen effluvium and trichodynia have also been reported. OBJECTIVE: To evaluate the presence of trichodynia and telogen effluvium in patients with COVID-19 and describe their characteristics in relation to the other signs and symptoms of the disease. METHODS: Patients with a history of COVID-19 presenting to the clinics of a group of hair experts because of telogen effluvium and/or scalp symptoms were questioned about their hair signs and symptoms in relation to the severity of COVID-19 and associated symptoms. RESULTS: Data from 128 patients were collected. Telogen effluvium was observed in 66.3% of the patients and trichodynia in 58.4%. Trichodynia was associated with telogen effluvium in 42.4% of the cases and anosmia and ageusia in 66.1% and 44.1% of the cases, respectively. In majority (62.5%) of the patients, the hair signs and symptoms started within the first month after COVID-19 diagnosis, and in 47.8% of the patients, these started after 12 weeks or more. LIMITATIONS: The recruitment of patients in specialized hair clinics, lack of a control group, and lack of recording of patient comorbidities. CONCLUSION: The severity of postviral telogen effluvium observed in patients with a history of COVID-19 infection may be influenced by COVID-19 severity. We identified early-onset (<4 weeks) and late-onset (>12 weeks) telogen effluvium.

Tinea Capitis Presenting as Diffuse Hair Loss and Significance of Trichoscopy: Four Case Reports.

Tinea capitis is a common fungal infection in children but is less frequently encountered in adults. Tinea capitis presenting as diffuse hair loss is a rare presentation. When patient presents with a diffuse hair loss, tinea capitis is not commonly thought of as differential diagnosis. Low clinical suspicion can lead to inappropriate empiric treatments that delay diagnosis. Trichoscopy in tinea capitis obviates the need for lengthy and invasive procedure or even KOH examinations in the absence of a side lab for diagnosing this common scalp disorder and also avoids misdiagnosis. Trichoscopy not only differentiates tinea capitis from female patterned hair loss but also aids in differentiating ectothrix from endothrix. Here, we present case reports of tinea capitis masquerading as female pattern hair loss with trichoscopy aiding in diagnosis of endothrix infection.

Long-Term Utility of Follicular Unit Excision in Lichen Planopilaris-Correlation of Graft Survival With Histopathological and Ultrasound Biomicroscopic Parameters.

BACKGROUND: Hair transplantation in scarring alopecia is challenging and transplant surgeons are hesitant due to fear of poor graft survival apart from the risk of reactivating the disease. OBJECTIVE: Survival rate of hair follicles transplanted in cases of lichen planopilaris (LPP). To correlate histopathological and ultrasonography findings and their impact on graft survival. METHODS: In 32 patients of inactive LPP included, a 5-cm2 recipient area was tattooed. The follicular unit density of the transplanted area was 20 to 25 FU/cm2. Postoperative follow-up was conducted at 6, 12, and 24 months. The recipient area density and ultrasound biomicroscopic parameters were assessed at each follow-up visit. RESULTS: The survival of grafts was 78.62% at 12 months, and 79.96% at 24 months. Histopathology variables studied at the time of transplantation such as epidermal atrophy, fibrosis, and inflammatory infiltrate were not found to have any effect on the graft survival. Ultrasonography parameters of the involved scalp skin were found to be markedly improved on follow-up. This suggests that the overall health of the scalp improved after hair transplantation. CONCLUSION: Follicular unit excision is a ray of hope for cases of primary cicatricial alopecia such as LPP because the result is satisfying to both the patient as well as the doctor.
